One of the key research issues in Reverse Engineering is the geometric modeling of complex surface.

逆向工程是20世纪80年代发展起来的一门新技术，其研究重点之一是复杂曲面零件的几何模型重构[1]。

Through comparison with finite element method, it has been demonstrated that boundary clement method is an effective method in the analysis of some complicatedly loaded parts and local stress concentration areas on loaders.

通过与有限元法比较表明，边界元法是分析装载机某些受力复杂零件和局部应力集中区域的有效分析工具。

Based on analysis of large part process features and adopting principles of object oriented as well as feature technology tasks were classified according to process type and complicatedness sequence feature library was set up accordingly .

在实际应用时，先依据具体零件的工艺特点和所包含的工艺种类，利用工艺特征库构造面向任务管理的工艺特征模型，并以此进行任务划分和分派。

And the use of convex and concave parts MasterCAM mode of a processing line tool design and manufacturing process simulation.

并运用MasterCAM 对零件的凸凹模进行了加工走刀路线的设计并模拟其加工过程。

With this scheme, however, technologist found that there are a series of small concavity on the edge of the blade, and it can become the most reason that cause the reject, extremely.

然而在实际加工中，工艺人员发现使用这种方法加工出的叶片在缘头部位会出现连续的小坑，严重时还可导致零件报废。

Due to improper assembly or pipe load and other reasons, so that part concentricity damaged, should be re-assembled.

由于装配不当或管道载荷等原因，使零件同心度遭到破坏，应重新装配。

The concentricity of the two holes in the bolster is specified to be smaller than

锭胆壳为精纺机上一个重要零件，其上有二个内孔规定其同心度。025毫米。

The supporting materials were used in manufacturing parts with Shape Deposition Manufacturing Technology. The supporting materials should be of rapidly concretionary so as to rapidly prototype and manufacture ceramic parts.

采用形状沉积成型技术制造零件时需要支撑材料，此支撑材料应具有快速凝固的特性，以达到陶瓷制件快速成型的目的。

To meet the needs of CAD/CAPP concurrent designing in Computer Aided Concurrent Engineering. This paper investigates the key of integration system designing. The representation scheme for defining and operating form feature based on manufacture, the protrusion form feature exchanging and the UI of the system with a manufacture enviroment are presented. And also an OODM—UIMS developed by the author is introduced. The concurrent design of CAD/CAPP is the bottleneck in integrating process.

本文根据并行工程的要求，从构造基于并行、面向特征的CAD/CAM集成系统的思想出发，对系统的模式设计、基于加工的零件参数化特征描述、凸起形状特征的转换处理及具有加工环境的系统交互界面及面向对象的交互界面管理系统的设计与开发等关键技术进行了深入的研究，形成了系统的思想理论和方法。

Combined with National Nature Science Fund project"Study on Modular Flexible Machining Cell Oriented Concurrent Design Software Tools", and aimed at Flexible Transfer Line product design for prism type parts, this dissertation systematically analyze the implement principle of computer aided concurrent design for complicated mechanical product.

本文结合国家自然科学基金项目"模块化柔性加工单元并行设计软工具的研究"（编号59575037），以棱体类零件柔性生产线（Flexible Transfer Line，简称FTL）产品设计为研究对象，系统地分析了复杂机械产品计算机辅助并行设计的实施机理，并对以下几方面的关键技术进行了深入地研究： 1。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
